scottshoe Posted January 21, 2005 Report Share Posted January 21, 2005 Both of my oxygen sensors took a dump on my 97 STS. I think Autozone wants $60 each. I thought that was a little pricey, even for a Caddy. It's the pre-cat ones, both banks are bad. I was wondering if anyone has replaced theirs and if I should put Factory GM ones in or if they are all the same more or less. Link to comment Share on other sites More sharing options...
